Installation Flow
Reference information
Operation
When the delivered subrack has been equipped with boards in cabinet, you can skip the steps involving "Installing
Subrack" and "Installing Boards and Components".
NOTE
If boards have been installed on a PTN 7900-24 before delivery, do not remove any board or module (such as the fan
module) during transportation. To learn how to replace boards and modules after an installation is complete, see the
chapters "Installing the Subrack" and "Installing Boards and Components ".

ESD Protection
Always wear ESD gloves or an ESD wrist strap prior to contact with the equipment or before handling boards or IC chips
to prevent damage to sensitive components due to electrostatic discharge from the human body. Ensure that the ESD
wrist strap is properly grounded.
Pre-Installation Check
Ensure that the equipment room, cabinets, power supplies, ground cables, optical cables, and associated devices are
ready for installation. Start the installation according to the engineering design documents after confirming that all
conditions are met.
Bundling Cables
Binding intervals between cable ties or optical fiber binding straps inside the cabinet cannot exceed 250 mm. (Binding
intervals cannot exceed 200 mm for user cables.)
Binding intervals between cable ties for all cables and corrugated pipes outside the cabinet are determined based on the
distance between the two horizontal beams. If the cable trough does not contain any beams, the binding intervals
between cable ties cannot exceed 250 mm.
Safety Information
The equipment is heavy. To prevent human injuries or equipment damage, always use a lifting device to transport or
position the equipment. Use a pallet truck or heavy-duty flat-bed truck to transport the equipment on even ground, and
use a cargo lift to transport the equipment between different floors.
Always wear protective gloves when lifting or transporting a cabinet to prevent hand injuries or damage to the cabinet
surface. Operators must protect themselves first if the cabinet unexpectedly tilts or even turns over during delivery.
This document provides guidelines for quick hardware installation. It describes procedures for onsite installation,
but does not describe pre-delivery assembly.
Installation Precautions

Requirements and Precautions for Operating Boards
22
Always wear ESD gloves to operating a board to prevent damage to sensitive components.
Any vacant slot must be covered by a filler panel to
prevent foreign objects from entering the subrack or
system ventilation ducts. Foreign objects may
cause an NE failure.
Boards are fragile and vulnerable. When transporting or placing a board, exercise caution and ensure that
the board is packed in a dedicated box to protect the board against damage.
Boards must be packed with original packaging materials during transportation. If the original packaging
materials are lost, contact Huawei technical support personnel.
Hold the protection plate under the board with hands and handle with care.

Before installing a subrack into a cabinet, remove the front door and side panels of the cabinet. For details,
see the N63B Cabinet Installation Guide.
To prevent human injuries or damage to the subrack, at least four people are required during the installation:
one to hold the subrack, the other to install the subrack.
Installing a Subrack
1 Installing the Subrack
The subrack is the basic unit of the OptiX
PTN 7900-24 and is used to house various
types of boards.
The N63B cabinet can be equipped with
one OptiX PTN 7900-24 subrack.

portion slots, ensure that the ejector levers are on the left side of the front
panels. When installing service boards or filler panels into lower-portion slots,
ensure that the ejector levers are on the right side of the front panels. After
installing the boards, ensure that vacant slots are covered with filler panels for
heat dissipation.
Wear an ESD wrist strap or ESD gloves
during operations.
Turn the ejector levers on the board
inward until the board cannot move
forward. Then, fix the board to the slot
of the cabinet.

2 Installing Fan powered box
Determine the mounting direction of the
Fan powered box and push it into the
slot.
Press the button on each side of the Fan powered box and insert the Fan
powered box until it is fully seated in the slot. After releasing the buttons, check
whether they are restored to their original positions. If they are not, withdraw
the Fan powered box, restore the buttons to their original positions, and then
install the Fan powered box again.
A yellow-green button is located on the
left and right sides of a Fan powered box.
You must press these two buttons to
completely insert the fan module into the
subrack or to remove it from the slot.
Button
The air flows in the upper and lower portions of a cabinet are in opposite directions, so the Fan powered boxes at the top and bottom of
the cabinet are installed differently.
Four labels are located on the Fan powered box: two on the top surface and two on the bottom. One of the labels, a mounting direction
label, indicates the mounting direction of the fan module. Another mounting direction label is present on the air blocking panel that covers
a vacant Fan powered box slot or inside the Fan powered box slot.
When installing a Fan powered box in the upper portion of a cabinet, ensure that the mounting direction label on the right of the Fan
powered box surface faces upward. When installing a Fan powered box in the lower portion of a cabinet, ensure that the mounting
direction label on the left of the Fan powered box surface faces upward.
The Fan powered box is designed for easy
installation. If you feel a blockage when
inserting a Fan powered box into a slot,
remove the Fan powered box and check
whether it was inserted correctly or whether
it is of the correct type. Do not use force to
insert the Fan powered box.

The OptiX PTN 7900-24 can import 6 independent power channels from the
first power cabinet into the PDU, including 3 working channels (A1 to A3) and
3 protection channels (B1 to B3). For each channel of PDU boards, the rated
input voltage is -48 V, and output power is 2400 W.
The input A1 to A3 channels correspond to the output a1 to a3 channels, and
the input B1 to B3 channels correspond to the output b1 to b3 channels.
NOTE If no short copper fitting is used, use the
3+3 or 2+2 power supply mode. The rated
input current of each channel is 63 A.
